WATCH-CAS E.

SPECIFICATEON forming part of Letters Patent No. 359,885, dated March22,1 Si '7.

Application tiled November E4. 1R85.

T @ZZ whom it may concern:

Be it known that I, DANIEL OHARA, of Waltham, in the county of Middlesexand State of Massachusetts, have invented certain new and usefulImprovements in Watch-Cases, of which the following is a full, clear,and exact description.

rlhis invention relates to the Fitch watchcase, so known in the trade,and for a more 1o particular description of which reference is -had tothe Letters Patent of the United States issued to Ezra (l. Fitch, datedApril 22,1879, No. 214,642.

The invention consists of a watch-case com- I5 posed of a center orshell, a back to the center, and a riser at the front thereof for theattachment of a front cap or bezel, all in one piece, in combinationwith a vsupplemental ring iitting and seating` upon a shoulder or ilat2o of and at the front of the case-center and a verse section of awatch-case having the movey ment-ring jointed or hinged within the casev3o center or shell in accordance with this invention and showing apendant-knob in side View.

Fig. 2 is a face View of the watch-case of Fig.

1 with the crystal and bezel-ring removed.

Fig. 3 is a transverse section in detail and at one side, showing abackcap orplate snapped upon the supplemental ring surrounding themovement-ring. Figs. 4 andare of a watchcase having the case center orshell in the form of an annulus and made separate from the 4o back cap,shown as in one piece with the casecenter in the preceding figures, andboth are transverse sections in detail, at one side only,

of the watclrcase and its attachments, and

show in each instance the combination of 4 5 movement-ring andsupplemental ring surrounding and hinged to it of this invention appliedthereto.

In the drawings, A represents the case center or shell, formed, as shownin Figs. 1, 2, and

5o 3, in one seamless piece of a concave shape,

Serial No. 183,983. (No model.)

open at one side, (the front 13,) and closed at its other side, (theback C,) and al1 so as to be suitable to receive a watclrmovementcarried by a ring, D, which is hinged or jointed at one side, as at E,and is vsurrounded by a supplemental ring, F, preferably shouldered, asat a, interiorly for a rest of a corresponding exterior shoulder, b, ofthe movement-ring D, and also shaped exteriorly with a shoulder, f, torest upon a corresponding shoulder, g, 6o around the inner periphery ofthe case-center. The construction of case center or shell A, abovedescribed, and illustrated in Figs. l, 2, and 3, constitutes no part ofthis invention, and therefore needs no further description herein, itbeing deemed sufficient to observe that it is in substance the same asdescribed and shown in the Letters Patent before cited, and to whichreference is hereby had i'or a more particular description thereof. 7o

In Figs. 4 and 5 the case center or shell is in the form of an annulus,open at both front and back, and at the front, (Fig. 4,) closed byacrystal, G, securedin abezelring, H, snapped over the outside of theriser J, and (Fig. 5) 75 also with a front cap, K, snapped over theoutside of a riser, L, and at the back, Figs. 4 and 5, with inner andouter back caps or plates, M N, each snapped over separate risers O I?of the case-center, all as well known, and 8o constituting no part ofthis invention.

The jointing or hinging of the movementring to the supplemental ring maybe in any of the well-known or other suitable ways, and consists insubstance of a part, h, on the movement-ring and a part, k, on thesupple mental ring, the one part fitting into an opening of the otherpart, and the two thenjointed together with a pintle, d, on which themovement-ring is to turn orswi ng, said pintle being 9o stationary andfixed in the part of the hinge on the supplemental ring. The jointing orhinging particularly described forms no part of this invention, and theinvention is not to be limited in any particular to any construction ofthe hinge or joint E.

The combination of a supplemental ring, F, with the movement-ring D, asdescribed, places thejoint or hinge E inside of the riser at the frontof the case, and to which the front bezelloo ring or cap-plate isattached, and thus does away with the placing` of thejoint in saidriseran important advantage, and especially when such riser isscrew-threaded for screwing the front bezel-ring or a cap-plate thereon,as, for

instance, as shownin Figs. l, 2, and 3.

The supplemental ring F, at its inner edge m, has a riser, a, of theordinary orother suitable construction, for the attachment of a cap 0rplate, Q, which may be made of albata or other suitable material, andshaped so that attached it will (Fig. 8) bear against the inner surfaceofthe back cap or plate, C, ofthe watchcase and act to brace and stiftenthe same.

The attachment ol" the albata or other metal cap or plate Q to thesupplemental ring` inay be made by adapting` the parts to be screwed oneupon the other or otherwise, in any suitable or well-known manner.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. A watchcase constructed with integral back, center, and riser atVi'ront of center, with flats inside and outside of riser, incombination with a front bezel or cap to ht said riser and said outsidedat, a supplemental ring to iit within andvto seat on said inside fiatot' caseccnter, and a inovenientrring,` hinged to and fitting withinsaid supplemental ring, subs stantially as described.

2. A watch-case constructed with integral back, center, and riser ati'ront of center, with Hats inside and outside of riser, in combinationwith a front bezel or cap to lit said riser and said outside lat, asupplen'iental ring to fit within and to rest on said inside flat ofcasecenter, a movement-ring` hinged to and iittin` with saidsupplemental ring, and a back cap or plate secured to the supplementalring, substantially as described.

In testimony whereof I have hereunto set my hand in the presence oi' twosubscribing,` witnesses.
